I am unsure of the exact episode, but there is a Yellow Maverick Grabber on top of a car carrier that gets jumped by the General Lee.
Cool.. Did you know those Chargers were usually junked after the jump??? Unibodies were so badly bent weren't considered safe for a second jump... They had a hauler(maybe one with Maverick? Naah not that thing) that went around country picking up Chargers that had been bought for show use...
